I finally managed to get the pH right using potassium hydroxide. I'm adjusting the wires to train the plants every couple of days.
This week I will feed them with a solution of NPK 5-7.5-10 + micronutrients.
Lol, schöne Arbeit. Machst du so etwas öfter? Irgendwie faszinierend.
Lol jetzt hast mich angesteckt. Meine Auto Destroyer wird jetzt auch ein Bonsai Bansai grow. D
Thanks @KingSalomonsWeed ! This is my first grow, actually! I have some bonsai experience, but no normal bonsai grows as fast as this. Usually wires (for LST) are adjusted a couple of times a year. This requires adjusting them every couple of days 😆 When I'll start with lollipopping I'll take some shots to better show the training applied.
